Description
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows any authenticated user to publish templated system announcements via POST /sys/api/sendBusTemplateAnnouncement. Low-privileged attackers can supply templateCode, toUser, and a forged fromUser to send notifications to arbitrary users through WebSocket, DingTalk, WeCom, Feishu and UniPush channels.
